Abstract

Strategy card game is a well-known genre that is demanding on the intelligent game-play and can be an ideal test-bench for AI. Previous work combines an end-to-end policy function and an optimistic smooth fictitious play, which shows promising performances on the strategy card game Legend of Code and Magic. In this work, we apply such algorithms to Hearthstone, a famous commercial game that is more complicated in game rules and mechanisms. We further propose several improved techniques and consequently achieve significant progress. For a machine-vs-human test we invite a Hearthstone streamer whose best rank was top 10 of the official league in China region that is estimated to be of millions of players. Our models defeat the human player in all Best-of-5 tournaments of full games (including both deck building and battle), showing a strong capability of decision making., Comment: cog2023 full

Abstract

Deep Reinforcement Learning combined with Fictitious Play shows impressive results on many benchmark games, most of which are, however, single-stage. In contrast, real-world decision making problems may consist of multiple stages, where the observation spaces and the action spaces can be completely different across stages. We study a two-stage strategy card game Legends of Code and Magic and propose an end-to-end policy to address the difficulties that arise in multi-stage game. We also propose an optimistic smooth fictitious play algorithm to find the Nash Equilibrium for the two-player game. Our approach wins double championships of COG2022 competition. Extensive studies verify and show the advancement of our approach.

Abstract

Transition Radiation (TR) plays an important role in particle identification in high-energy physics and its characteristics provide a feasible method of energy calibration in the energy range up to 10 TeV, which is of interest for dark matter searches in cosmic rays. In a Transition Radiation Detector (TRD), the TR signal is superimposed onto the ionization energy loss signal induced by incident charged particles. In order to make the TR signal stand out from the background of ionization energy loss in a significant way, we optimized both the radiators and the detector. We have designed a new prototype of regular radiator optimized for a maximal TR photon yield, combined with the Side-On TRD which is supposed to improve the detection efficiency of TR. We started a test beam experiment with the Side-On TRD at Conseil Europ\'{e}en pour la Recherche Nucl\'{e}aire (CERN), and found that the experimental data is consistent with the simulation results., Comment: 13 pages, 10 figures, 2 tables

Abstract

The Gamma-Ray Integrated Detectors (GRID) is a space mission concept dedicated to monitoring the transient gamma-ray sky in the energy range from 10 keV to 2 MeV using scintillation detectors onboard CubeSats in low Earth orbits. The primary targets of GRID are the gamma-ray bursts (GRBs) in the local universe. The scientific goal of GRID is, in synergy with ground-based gravitational wave (GW) detectors such as LIGO and VIRGO, to accumulate a sample of GRBs associated with the merger of two compact stars and study jets and related physics of those objects. It also involves observing and studying other gamma-ray transients such as long GRBs, soft gamma-ray repeaters, terrestrial gamma-ray flashes, and solar flares. With multiple CubeSats in various orbits, GRID is unaffected by the Earth occultation and serves as a full-time and all-sky monitor. Assuming a horizon of 200 Mpc for ground-based GW detectors, we expect to see a few associated GW-GRB events per year. With about 10 CubeSats in operation, GRID is capable of localizing a faint GRB like 170817A with a 90% error radius of about 10 degrees, through triangulation and flux modulation. GRID is proposed and developed by students, with considerable contribution from undergraduate students, and will remain operated as a student project in the future. The current GRID collaboration involves more than 20 institutes and keeps growing. On August 29th, the first GRID detector onboard a CubeSat was launched into a Sun-synchronous orbit and is currently under test., Comment: accepted for publication in Experimental Astronomy

Abstract

The increasing level of digitisation and rapid digital technology innovation has led to a fundamental revolution in the fashion industry, significantly reflected in the area of social media marketing (SMM). No longer passive receivers of content, customers now seek opportunities to get involved in various (SMM) activities, particularly in the fashion context. For instance, Chinese fashion shoppers spend less than 0.5% of their online time on the official websites of brands or companies, while 80% of online time is accounted by social networks. Thus, customers are increasingly taking on new social roles in the value co-creation processes by interacting and cooperating with brands and other customers on social networking platforms. One form of value co-creation is dialogic co-creation, which refers to customers sharing information and opinions about products or brands via electronic word-of-mouth (e-WOM). The aim of this research is to enhance the understanding towards Chinese fast fashion customer engagement behaviours in dialogic co-creation activities relating to international fast fashion brands and other customers on a Chinese social networking site, Sina Weibo. According to the theory of Customer-Dominant Logic (Heinonen and Strandvik, 2015), this research investigates customer logic, customer value formation process and the consequence of customer engagement in dialogic co-creation based on this research context. In the literature review, it identifies the antecedent factors that can reflect customer logic on customers' engagement behaviours and preferences. Consumer expertise and social expertise are considered as two key drivers to influence customer engagement behaviour. Furthermore, it identifies that organic e-WOM, amplified e-WOM, entertainment and remuneration are the four popular topics of dialogic co-creation activities in which fashion customers to engage. In addition, customer benefits and customer purchase intention are deemed as the positive outcomes from customer engagement in value formation process on social networking sites. A mixed method approach (qualitative netnography and quantitative online survey) is employed to explore and test the conceptual framework that outlines the process of customer engagement in dialogic co-creation activities on a social networking site (SNS). In stage one, a netnographic analysis of 3,000 pieces of both customer-generated and brand-generated comments on Sina Weibo is conducted to confirm the antecedent factors that motivate customer to create and co-create dialogues with international fast fashion brands and other customers on a SNS. Furthermore, through analysing 300 pieces of brand-generated posts, it categorises the different types of social media marketing activities customers engage in for dialogic co-creation on a SNS. In stage two, an online survey is employed to test the conceptual model developed from literature review to validate the relationships among customer logic, customer engagement in dialogic co-creation activities and the consequences. The research findings provide valuable implications for both academia and practice in the field of marketing communication, customer engagement and dialogic co-creation. The tested conceptual model provides a holistic understanding of customer logic, customer engagement in dialogic co-creation activities on a SNS and the consequences of such engagement from a customer perspective. The research findings also hold essential implications for the international fashion marketers to understand Chinese customers' online social behaviours and preferences, thereby to facilitate appropriate social media marketing strategies on Chinese social networking platform and assist customer engaging in value formation process.
